Abstract
The present invention relates to a solid electrolyte comprising a sulfide-based compound and an all-solid-state battery applied therewith and, more particularly, to a solid electrolyte comprising a sulfide-based compound that is free of phosphorus (P) element but exhibits high ionic conductivity, and an all-solid-state battery applied therewith. The sulfide-based solid electrolyte and the all-solid-state battery applied therewith according to the present invention exhibit improved reactivity to moisture to prevent the generation of toxic gas, resulting in an improvement in safety and stability and do not reduce in ion conductivity even after being left in air, and the solid electrolyte is easy to handle and store thanks to the improved shelf stability thereof.
